Can heads of state be prosecuted for genocide by international courts?
Yes, heads of state can be prosecuted for genocide by international courts. Under international law, an individual's official position, including that of a head of state, does not provide immunity or a basis for avoiding criminal culpability for genocide, war crimes, or crimes against humanity.12
While heads of state may benefit from immunity under national laws, this defense is not available before international tribunals. For example, the statutes of the International Criminal Tribunal for the Former Yugoslavia (ICTY) and the International Criminal Tribunal for Rwanda explicitly rejected official position as a shield against prosecution. Consequently, the ICTY indicted sitting Yugoslav president Slobodan Milošević in 1999.21
Similarly, the International Criminal Court (ICC) has sought the arrest of sitting heads of state, such as Sudanese president Omar al-Bashir and Russian president Vladimir Putin, for their alleged roles in international crimes. Holding leaders accountable for such atrocities is a fundamental principle of international justice, ensuring that those who orchestrate or permit mass violence cannot hide behind the office they hold.342
